[libvirt] [PATCH 0/6 v3] Shared disk table related fixes/improvements

Inspires by the crash when using CD-ROM or Floppy with empty source, except the fixes for the crashes, this also enrichs the hash table with a list of names of domain which use the shared disk. And to keep the hash table to be in consistent state, this also fixes the problems on adding/removing the hash entry when updateing/ejecting media of CD-ROM or Floppy. And updates the hash table when reconnecting domain process. v2 - v3: * Rebase on the top * Small changes after more testing.
